Error on Julia v 0.6 #30

Open mirestrepo opened 7 years ago

mirestrepo commented 7 years ago

After upgrading to Julia v0.6 ERROR: LoadError: Module ScikitLearn declares precompile(true) but require failed to create a usable precompiled cache file. Stacktrace:

running Pkg.build("ScikitLearn") after fixes it but should that be necessary?

cstjean commented 7 years ago

Yeah, I've hit that a few times during the 0.6 alpha period, but restarting Julia usually solved the problem. I've never used Pkg.build("ScikitLearn"). I posted a question about it on Discourse, we'll see if there's a solution. Thank you for the bug report.

Possibly related to JuliaLang/julia#18150 and JuliaLang/julia#12508 ... precompiling succeeds, but it can't be loaded because you already have an older conflicting version of a module loaded. Nothing to do but to restart Julia.

cstjean commented 7 years ago

Ok, thank you for looking into it.

I've been having this issue with 0.6.2. Restarting did make the problem go away. However, when I run from within Atom, the problem refuses to go away, even after restarting atom. I'm guessing there are some strange interactions going on with https://github.com/JunoLab/Atom.jl

Same. In Atom I'm getting error:

julia> using ScikitLearn
INFO: Recompiling stale cache file /Users/harry/.julia/lib/v0.6/ScikitLearn.ji for module ScikitLearn.
WARNING: The call to compilecache failed to create a usable precompiled cache file for module ScikitLearn. Got:
WARNING: Module Iterators uuid did not match cache file.

But import works fine in the REPL.

Same is the case with my system. Error when using in Atom but not otherwise.

stevengj commented 6 years ago

Probably you should file an issue with JunoLab/atom-julia-client Atom.jl … I'm guessing there is some issue with the Julia process persisting even when you quit Atom?

cstjean commented 6 years ago

I'm pretty sure that these problems are caused by the hokey reexporting I do in the submodules. I just don't have time to fix it at the moment (would welcome a PR if anyone's interested, but it's not trivial).

Does anyone object if I turn off precompilation in the meanwhile? It seems to affect many users.
